Solve f-3/4=1 1/2 using addition subtraction multiplication or division

f = 2 1/4

Step-by-step explanation:

f-3/4=1 1/2

Add 3/4 to each side

f-3/4+3/4=1 1/2+3/4

f = 1 1/2 +3/4

Get a common denominator

f=  1 2/4 + 3/4

  = 1 5/4

  = 1 + 4/4 + 1/4

  = 2 1/4

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)
