Grade 6 math ration help

" Write an equivalent ratio with 20 as one of the terms. "
a ) 4:5
b ) 2:8
c ) 7:4
d ) 10:3

you have to find the factor that makes the first term equal 20. for example 4x5=20 so you also have to mulitply 5 times five (25).
a)20:25
b)20:80
c) 35:20
d)20:6

a) 4 * 5 = 20 So, multiply each term by 4.
4(4) : 4(5)
16:20

OR

Multiply each term by 5.

5(4) : 5(5)
20:25

b) 2 * 10 = 20 So, multiply each term by 10.
10(2) : 10(8)
20:80

c) 4 * 5 = 20 So, multiply each term by 5.
5(7) : 5(4)
35:20

d) 10 * 2 = 20 So, multiply each term by 2.
2(10) : 2(3)
20:6

16:20
20:80
35:20
20:6

all you have to do is make one value 20 and use the same operation on the other value.

I cant believe your just now learning that in sixth grade.

20:25
20:80
35:20
20:6

I can't tell if you're joking with this question or lazy/stupid, but is a set of answers.

16:20
20:80
35:20
20:6
