<h3 /><h3>Amount John have left</h3>

John  earned $45.90 during the summer break.

He used 1 / 6 of the money to buy trading card. Then he used the following amount to buy the trading card.

  • 1 / 6 × 45.90 = $7.65

Then, he used 3/5 of the remaining amount to buy a sketchbook, and also spends $4.50. Therefore, the total he spends can be computed as follows:

  • 3 / 5 × (45.90 - 7.65) + 4.50 = 22.95 + 4.50 = $27.45

So, He spent

  • $7.65 on trading cards
  • $22.95 on sketch book
  • $4.50 on comic book.

The amount he has left = 45.90 - 7.65 - 22.95 - 4.50 = $10.8

Oxana [17]

the ratio of the number of kids is 4:7

that means for every 7 kids we have 4 adults

7 kids ---- 4 adults

the difference is 3

we dived the difference of the kids between the difference of the ratio

150/3 = 50

the number we obtained must be multiply by the ratio of each part

7(50) = 350 number of kids

4(50)=200 number of adults

at a restaurant the ratio of kids meals sold to adults meal was 5:4. if there were 20 kids meals sold, what is the combined amou
seraphim [82]
I would set up a proportion:

\frac{20}{x}=\frac{5}{4}

The proportion basically says, "if there are 5 kids meals for every 4 adult meals, that means 20 kids meals would mean x adult meals."  Just cross multiply and then solve for x:

\frac{20}{x}=\frac{5}{4}\\5x=80\\x=16

That means there are 20 kids meals sold and 16 adult meals sold, so the result is:

36 meals in total.
