Question

Christian has 1/2 of a foot of tape. His friend gives him 3/10 of a foot of tape. How much tape does Christian have now?

Answer 1

4/5 foot

Explanation:

Add the lengths together

1/2 +3/10

Get a common denominator

1/2 *5/5 + 3/10

5/10 + 3/10

8/10

Simplify the fraction by dividing the top and bottom by 2

4/5

Answer 2

`\rm \implies \: Total \: \: length \: \: of \: \: tape \: = \: (1)/(2) \: + \: (3)/(10) \\`

• Now , we take LCM of denominators.

• LCM of 2 and 10 is 10.

`\bf \large \rightarrow \: \: (5 \: + \: 3)/(10) \: = \: (8)/(10) \\`

Now , simplifying the fraction in simplest form.

`\bf \large \rightarrow \: \: \cancel(8 \: \: ^(4) )/(10 \: \: ^(5) ) \: = (4)/(5) \\`

Christian have 4/5 foot of tape have now.
