Question

Rob had $210. He spent 4/7 of it. How much money did he have left?​

Answer 1

90

Explanation:

210 divided by 7 is 30 and times 3 is 90

Answer 2

`\boxed{ \bold{ \huge{ \boxed{ \sf{90 \: dollars}}}}}`

Explanation:

Total amount of money that Rob had = $ 210

Total amount of money that he spent =
`\sf{ (4)/(7) * 210} = \: 120 \: dollars`

Finding the amount of remaining money

`\boxed{ \sf{total \: amount \: of \: money \: that \: he \: had \: - \: total \: amount \: of \: money \: that \: he \: spent}}`

`\dashrightarrow{ \sf{210 - 120}}`

`\dashrightarrow{ \sf{90 \: dollars}}`
