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
Answer:
The number is 6
Step-by-step explanation:
Let's say that the reciprocal of the number is x
1/2 + 3 = 1
3x = 1/2
divided both sides by 3
x = 1/6
Since x is the reciprocal of the number, flip 1/6 and you will get 6/1
6/1 is really just 6 so that's your answer.
Hope this helps :)
