Question

1/2 +b=1 3/4 What does b represent and how to solve it?

Answer 1

Answer:

b represents the unknown number, the number that we are finding by solving this equation

b = 1 1/4

or, in decimal form

1.25 = b

Step-by-step explanation:

1/2 + b = 1 3/4

b = 1 3/4 - 1/2     ------------>      1/2 = 2/4

b = 1 3/4 - 2/4

b = 1 1/4

or, in decimal form

1.25 = b

b represents the unknown number, the number that we are finding by solving this equation

Answer 2

Answer:

b= 5/4 or 1 1/4

Step-by-step explanation:

First I will make 1 3/4 into an improper fraction

1/2 + b = 7/4

Then I will make the fractions have common denominators

2/4 + b = 7/4

I subtract 2/4 from 7/4

b= 5/4
