Answer:

=2 7/12 is needed on sunday

Step-by-step explanation:

Friday + Saturday + Sunday = total time studying

1 1/4 + 2 2/3 + sunday = 6 1/2

Get a common denominator of 12

1/4*3/3 =3/12

2/3 *4/4 =8/12

1/2 *6/6=6/12

1 3/12 + 2 8/12 + sunday = 6 6/12

Combine terms

3 11/12 + sunday = 6 6/12

Subtract 3 11/12 from each side

3 11/12 - 3 11/12 + sunday = 6 6/12 - 3 11/12

sunday = 6 6/12 - 3 11/12

Borrow 1 from 6 in the form of 12/12

sunday = 5 + 12/12+ 6/12 - 3 11/12

= 5 18/12 - 3 11/12

=2 7/12

How do you split an uneven number in half like 9

ollegr [7]

You would split an uneven number in half, by multiplying the uneven number by 5, and adding a decimal in between the numbers. (i.e. 9 x 5 = 45 = 4.5) Hope this helps:)
