Answer:
4 3/4
Step-by-step explanation:
= (8 - 3) + (1/4 - 1/2)
= 5 + 1/4 - (1 x 2 over 2 x 2)
= 5 + 1/4 - 2/4
= 5 and (1/2 over 4)
= 5 + -1/4
= 4 3/4
To add fractions together, you must convert the smaller fraction (
) to a denominator that matches the other fractions denominator.
In this case, 1/2 would become 4/8
We can add 4/8 to 7/8 to get 11/8
Then we can add the 1 to it, which acts as 8.
Which gives us 19/8
Or 2 3/8
So 28=8
35 more would be 63 so
28=8
63=x
Cross multiply and 28x=504
x=18
