3/4x - 4= 1/2
add 4 to both sides
3/4x= 4 1/2
change 4 1/2 to improper fraction
3/4x= 9/2
divide both sides by 3/4
x= 9/2 ÷ 3/4
multiply by inverse of 3/4
x= 9/2 * 4/3
x= (9*4)/(2*3)
x= 36/6
x= 6

CHECK
3/4x - 4= 1/2
3/4(6) - 4= 1/2
18/4 - 4= 1/2
4 2/4 - 4= 1/2
4 1/2 - 4= 1/2
1/2= 1/2

Dennis and Ivy share some sweets between them in the ratio 7:4 Dennis got 42 sweets. How many does ivy get

MrRa [10]

Answer:

$Ivy = 24$

Step-by-step explanation:

Given

$Dennis : Ivy = 7 : 4$

Required

Determine the amount of sweet Ivy gets when Dennis = 42

We have:

$Dennis : Ivy = 7 : 4$ and

$Dennis = 42$

Substitute 42 for Dennis in $Dennis : Ivy = 7 : 4$

$42 : Ivy = 7 : 4$

Convert to fraction

$\frac{42}{Ivy} = \frac{7}{4}$

Cross Multiply:

$Ivy * 7 = 42 * 4$

Divide through by 7

$\frac{Ivy * 7}{7} = \frac{42 * 4}{7}$

$Ivy = \frac{42 * 4}{7}$

$Ivy = 6* 4$

$Ivy = 24$
