1/4 = 5/20
2/5 = 8/20
8/20 + 5/20 = 13/20 has been spent
answer= x=20
Step-by-step explanation:
We have, 35% × x = 7
or,
35
100
× x = 7
Multiplying both sides by 100 and dividing both sides by 35,
we have x = 7 ×
100
35
x = 20
If you are using a calculator, simply enter 7×100÷35, which will give you the answer.
