Answer:
1/15 of their time is free time.
Step-by-step explanation:
To find the answer to this 2-step problem, we have to add all the fractions up, then find how much of that time is not part of the fraction.
So to add all the fractions, you have the equation:
1/4 + 3/5 + 1/12
The first thing we have to do is to find a common denominator.
4, 5, and 12 are each able to multiply into 60.
So we can make the equation now with a common denominator.
15/60+36/60+5/60=56/60.
We now can simplfy this.
56/60=14/15
Now that we know how long it is to do all the other activities, it tells us that the rest of the time is free time. To find the rest of the time, we have to do:
1-14/15=1/15
So 1/15 of their time is free time.
Answer is B. 2.19/Ib (just divide 4 by 8.76)
Need to find:
- Perimeter of new square formed?
Solution:
- Side of smaller square = 3cm.
- Side of Bigger square = 9cm
Using formula:
- Perimeter of square = 4 × side
<u>Perimeter of smaller </u><u>square:</u>
⟹ 4 × 3
⟹ 12 cm
<u>Perimeter of Bigger square:</u>
⟹ 4 × 9
⟹ 36cm
Perimeter of new square = Perimeter of Bigger square - Perimeter of smaller square
⟹ 36 - 12
⟹ 24 cm
∴ Perimeter of new square formed is 24 cm.
