This is a ratio question, is this correct?

C

Step-by-step explanation:

Before expressing as a ratio the quantities must have the same denomination

$2 = 200 cents, thus

40 cents : $2

= 40 cents : 200 cents ( divide both parts by 40 )

= 1 : 5 → C

b

step-by-step explanation:

the total is 23.97. 0.25% is off so you have to subtracting 25% from 100% and you will get 75% if you convert it to decimal you will get 0.75. you have to find the original because the formula is % times original = total.so you have the total and the % so you just have to plug it in.

1 x=22.52

2: 65/39=604+39x

65x-39x=604

26x=604

x=604/26

×=23.23
