There are 8 times 84s that are present in 672.
When 'a' is divided by 'b', then the result we get from the division is the part of 'a' that each one of 'b' items will get. Division can be interpreted as equally dividing the number that is being divided into total x parts, where x is the number of parts the given number is divided.
We need to find how many 84s are present in 672
We will simply divide the 84 by 672.
That is;
672/ 84
= 336/42
= 168/21
= 8
Hence, there are 8 times 84s that are present in 672.

Answer:
Area of the bookmar = 68.56 sq.cm.
Step-by-step explanation:
It is given that the diameter of each circle is the width of the rectangle.
Therefore, each radius = = 2 cm.
Area of the 2 semi circles = 2 × 0.5 × 3.14 ×
= 4 × 3.14
= 12.56 sq.cm.
Now, area of the rectangle = length × width
= 14 × 4
= 56 sq.cm
Area of the bookmark = Area of the rectangular part + 2 × (area of the semicircular part)
= 56 + 12.56
= 68.56 sq.cm.

Answer:
16 girls
Step-by-step explanation:
there are 4 out of 7 girls in the class.
28/7=4 (this is the unite rate per group number)
4 x 4 =16
Step-by-step explanation:
So 4:3 means for 4 girls there are 3 boys. In total, that would be 7.
So, we divide 28 by 7 for 4 meaning 1 in the 4:3 is 4.
And since we are dealing with girls, 4*4=16
To check, 4*3=12 Boys and 16+12=28
