How to write a whole number into a fraction in a subtraction problem

insens350 [35]

Im hoping you just want an example so here you go

whole number: 16
fraction version of 16: 16/1

to subtract fractions you have to have a common denominator.

so if i had a problem like 6 -1/3
step 1 would be to turn 6 into a fraction: 6/1
step 2 is to find the common denominator:
6/1 -1/3, in this case it is 3, so you multuply the first term by 3
you would then get 18/3 - 1/3, now all you do if subract numerators, 18-3=15

final answer would be 15/3, you can simplify it into 5/1 which is also 5

Simplify and solve each of the following equations.

inna [77]

Answer:

A. h = 4

B. g = 15

C. b = -6

D. b = 15

Step-by-step explanation:

A. 9h + 8 - 12 = -40

9h - 4 = -40

+ 4 + 4

9h = -36

$\frac{9h}{9} = \frac{-36}{9}$

h = -4

B. 9 + 6g + 1 = 100

10 + 6g = 100

- 10 - 10

6g = 90

$\frac{6g}{6} = \frac{90}{6}$

g = 15

C. -45 = 28 - 13 + 10b

-45 = 15 + 10b

- 15 - 15

-60 = 10b

$\frac{-60}{10} = \frac{10b}{10}$

b = -6

D. 37 = 11 +3b - 19

37 = 3b - 8

+ 8 + 8

45 = 3b

$\frac{45}{3} = \frac{3b}{3}$

15 = b
