Express your answer in simplest terms.

A. 4 1/4


B. 4 1/8


C. 5 5/8


D. 6 1/4

Answers

we can solve this by multiplying those two numbers but we place them in improper fraction.

2 1/2 x 2 1/4
becomes
5/2 x 9/4

for fraction multiplication, just multiply numerator by numerator and denominator by denominator

5/2 x 9/4 = 45/8

we can simplify this into mixed fraction while numbers in whole numbers and remainder in numerator

5 5/8 is the answer

How many sweets can you fit in a cylinder with diameter 3 cm and height 10 cm?

Answers

Well, we need the information of the dimensions and the volume of the sweets.

Because the volume of the cylinder is

\pi r^(2)h

r, radius, is half of the diameter, so 3/2=1.5
h is height
so the volume is
\pi r^(2)=\pi 1.5^(2) *10=70.65

(\pi=3.14, approximately)

now, let's say that each sweet has a volume of 1, we can then fit in 70 sweets. But since you forgot to give the dimentions or volume of the sweets, all i can say is: you need to divide 70.65 by the volume of the sweets!

What is 40.8 ÷ 6? Please explain how you got your answer​

Answers

Answer:

6.8

How many 6's can go into 40?

6 + 6 + 6 + 6 + 6 + 6 = 36

6 6's

Subtract the amount off

40.8-36=4.8

How many 6's can go into 4.8?

0.6 + 0.6 +0. 6 + 0.6 + 0.6 + 0.6 + 0.6 + 0.6 = 48

0.8 6's

4.8 = 4.8 = 0

6 6's + 0.8 6's = 6.8 6's

6.8 is the answer
