It is solved by unitary method.
Plz see the attachment....
I personally don’t know the answer so i can’t help
1st Convert into a top heavy fraction or improper fraction
<h3>
like for example 3 1/2 so you times the 3 by 2 which is 6 and add that one so it will be 7/2</h3><h3>
lets say your adding that to 2 1/2 you convert that which is 5/2 </h3><h3>
5/2 and 7/2 have the same denominator so you add 5 and 7=12 12/2 and 2 goes into 12 6x so it is just 6 </h3><h3>
THIS IS AN EXAMPLE</h3><h3>
TO REGROUP THEM </h3><h3>
Lets say its </h3><h2>21/4</h2><h3>YOU DIVIDE 21 BY 4 WHICH IS 5 WITH AN REMAINDER OF 1 SO YOU DO THAT 5 AS A BIG NUMBER AND THAT ONE GES ABOVE THE FOR LIKE 5

</h3><h3>SO I TRIED :)</h3>
Answer:
12 3/4 hours
Step-by-step explanation:
Jack spends 1 1/2 times as long on his homework as Jill .
Jill spends 8 1/2 in doing his home work .
Time spent by jack in doing his homework is jacks time multiplied by Jill’s
That’s
1 1/2 x 8 1/2
Change to improper fractions.
We have,
3/2 x 17/2
Multiply through
51/4 = 12 3/4
Jack spends 12 3/4 hours in doing his homework
