Answer:
a.
b. He saved 7,500
Step-by-step explanation:
a. Find the part given to his younger brother express it in fraction.
0.33 + 0.5 = 0.83
1 - 0.83 = 0.17 or 17/100
b. How much did he save?
15,000 x 0.5 = 7,500
Step-by-step explanation:
Total Earning (1 month): Php 15,000.00
33/100 (Php 15,000) = Php 4,950 buying ingredients
1/2 (Php 15,000) = Php 7,500 saved money
Total = Php 12,450
Php 15,000 - Php 12,450 = Php 2,550 remaining part that he gave to his younger brother
so for letter a,
33/100 + 1/2 + x = 1
83/100 + x = 1
x = 1 - 83/100
x = (100 - 83)/100
x = 17/100 part; .17 in decimal
