Divide 5kg in the ratio 13:7

3.25 Kg : 1.75 Kg

Step-by-step explanation:

Sum the parts of the ratio, 13 + 7 = 20 parts

Divide the amount by 20 to find the value of one part of the ratio.

5 Kg ÷ 20 = 0.25 Kg ← value of 1 part of the ratio, thus

13 parts = 13 × 0.25  =3.25 Kg

7 parts = 7 × 0.25 = 1.75 Kg

step-by-step explanation:

$53.50

step-by-step explanation:

you have to subtract the amount of money chuck earned ($72.50) by the cost of the gas for the mower ($11.25) and the new string for the trimmer he bought ($7.75).

72.50-11.25=61.25

and then subtract $61.25 by the second thing he bought (the new string for the trimmer)

61.25-7.75=53.5

so in total it's $53.50 (53 dollars and 50 cents)
