Write a word problem that you can solve using multiples to estimate the quotient. include a solution

You have 21 candies and you want to share them among 4 friends. How many candies correspond to each one?

Step-by-step explanation:

Multiples of four are: 4 (= 4*1), 8 (= 4*2), 12 (= 4*3), 16 (= 4*4), 20 (= 4*5), 24 (= 4*6), ...

Then, 21/4 can be approximated as 20/4 = 5

(23*2)-12=x     x=34

step-by-step explanation:

a 4/6 = 9/12   not proportional

step-by-step explanation:

to find which are not proportional, we can use cross products

if it is true, they are proportional.   if it is not true, they are not proportional.

a 4/6 = 9/12

4* 12 = 6*9

48 = 54

not this is not proportional  

b 2/3 = 12/18  

2* 18 = 3 * 12

36 = 36

this is proportional

c 5/4 = 10/8  

5*8 = 4*10

40 = 40

this is proportional

d 7/5 = 35/25

7*25 = 5 * 35

175 = 175

is proportional
