Understand: She paid Php 232.90 for 4.5kg of rice.
Plan: Need to know how much did she pay per kilogram of rice. (Divide)
Solve: 232.90 divided by 4.5
4.5/232.90 (Need to move 4.5's decimal to the right so it will be a whole number but as you move the divisor's(4.5) decimal, you need to move the divident's(232.90) decimal to the right too.)
45/2329
2329 divided by 45 = 51.756(rounded up)
Check: 51.756 x 45 = 2329

Understand: Leah bought 4 t-shirts and 2 pairs of pants for 3000. Shirts cost 300
Plan: Need to find the cost of each pair of pants.
Solve: 3000 - (300 x 4)
3000 - 1200
3000 - 1200 = 1800
1800 divided by 2(pants)
1800 divided by 2 = 900
900 each pants
Check: (900 x 2) + (300 x 4)
1800 + 1200
1800 + 1200 = 3000
