Question

Bob earned $2100. He spent 1/5 of his money on rent and 1/3 of it on food. How much money did he have left?

Answer 1

He should have $980 left

Answer 2

Answer:

$980

Step-by-step explanation:

Step 1: Find $\frac{1}{5}$ of 2100 = 420

• $\frac{1}{5}\times \:2100$

• Convert 2100 to a fraction: $\:2100=\frac{2100}{1}$

• $=\frac{1}{5}\times \frac{2100}{1}$

• Cross Divide

• $2100 \div 5 = 420$

Step 2: Find $\frac{1}{3}$ of 2100 = 700

• $\frac{1}{3}\times \:2100$

• Convert 2100 to a fraction: $\:2100=\frac{2100}{1}$

• $=\frac{1}{3}\times \frac{2100}{1}$

• Cross Divide

• $2100 \div 3 = 700$

Step 3: Add both results together

$420 + 700 = 1120$

Step 4: Subtract the result from how much Bob earns ($2,100)

$2100 - 1120 = 980$

Bob has $960 left
