🔢 Converting Larger Units to Smaller Units: Use Multiplication [ × ]
Weeks to Days 1 wk = 7 days wk × 7 =
Years to Months 1 yr = 12 mos yr × 12 =
Years to Days 1 yr = 365 days yr × 365 =
Decades to Years 1 decade = 10 yrs dec × 10 =
Part A Use your calculator to convert each larger unit of time to the smaller unit.
1 15 weeks
= 105 days
2 32 years
= 384 months
3 9 years (standard)
= 3,285 days
4 48 weeks
= 336 days
5 14 years
= 168 months
6 6 decades
= 60 years
Part B Perform two operations on your calculator: multiply first [ × ], then add the remaining units [ + ].
7 18 weeks and 6 days
= 132 days
Calculator Keystrokes: [ 18 ] [ × ] [ 7 ] [ = ] 126  ➔  [ + ] [ 6 ] [ = ] 132 days

= 93 months
Calculator Keystrokes: [ 7 ] [ × ] [ 12 ] [ = ] 84  ➔  [ + ] [ 9 ] [ = ] 93 months

[ ÷ ] DIVIDE
➗ Converting Smaller to Larger Units: Divide [ ÷ ] & Find Remainder

Months to Years Divide by 12 mos ÷ 12 =
Days to Years Divide by 365 days ÷ 365 =
Finding Remainder Total − (Whole × Divisor) − product =
Part C Use calculator division [ ÷ ] to convert smaller time units into larger whole units.
11 308 days
= 44 weeks
12 180 months
= 15 years
13 2,190 days
= 6 years
14 581 days
= 83 weeks
15 264 months
= 22 years
16 3,650 days
= 10 years
Part D Divide on your calculator, record the whole quotient, and find the remainder using [ × ] and [ − ].
17 179 days
= 25 weeks and 4 days
Calculator Steps: 179 ÷ 7 = 25.57  ➔  25 × 7 = 175  ➔  179 − 175 = 4 days
18 115 months
= 9 years and 7 months
Calculator Steps: 115 ÷ 12 = 9.58  ➔  9 × 12 = 108  ➔  115 − 108 = 7 months
19 750 days (365 days/yr)
= 2 years and 20 days
Calculator Steps: 750 ÷ 365 = 2.05  ➔  2 × 365 = 730  ➔  750 − 730 = 20 days
20 410 days
= 58 weeks and 4 days
Calculator Steps: 410 ÷ 7 = 58.57  ➔  58 × 7 = 406  ➔  410 − 406 = 4 days

Part E Solve each real-world problem. Write your calculator operations and complete final answers.
21 Metro Manila Subway Tunnel Construction
A major infrastructure section of the Metro Manila Subway in Quezon City has an estimated construction timeline of 68 months. Using your calculator, convert this total timeline into years and months.
Calculator Working Space:
68 ÷ 12 = 5.66... ➔ 5 × 12 = 60 ➔ 68 − 60 = 8 months remainder
Answer: 5 years and 8 months
22 Barangay Reforestation Project
Volunteers planted native pine and mahogany seedlings over a continuous period of 385 days. The barangay captain requires the report in full weeks. Using calculator division, how many whole weeks did the planting last?
Calculator Working Space:
385 ÷ 7 = 55 (exact quotient with 0 remainder)
Answer: 55 weeks
23 Philippine Wildlife Sanctuary Records
A wildlife sanctuary recorded that an endangered eagle lived for 16 years, while a rescued civet cat lived for 140 months. Using your calculator, convert the eagle's age to months, then find the difference in months.
Calculator Working Space:
Eagle: 16 × 12 = 192 months ➔ Difference: 192 − 140 = 52 months
Answer: Eagle: 192 mos (52 mos longer)
24 School Centennial Celebration Countdown
A central school is preparing for its 100th anniversary in exactly 2 years and 35 weeks. Using your calculator (365 days/year and 7 days/week), calculate the total number of days remaining until the centennial day.
Calculator Working Space:
Years: 2 × 365 = 730 ➔ Weeks: 35 × 7 = 245 ➔ Total: 730 + 245 = 975 days
Answer: 975 days
