Answer:
The first one
Explanation:
9 and 1/4 are both rational numbers (which are numbers that can be represented in a fraction; 9 can be represented as 9/1)
And since it equals to 9/4 (or 2 1/4) the product is also a rational number.
4x + 3x = 28
7x = 28
7x/7 = 28/7
X = 4
Girls = 4
4x4 = 16
16 girls
12
1/2 * x =6
6/ (1/2) = x
X=12
Answer:
Multiply both the divisor and the dividend by 10 to make it easier to divide
Step-by-step explanation:
As given division equation in a more suitable format that shows the dividend and the divisor that is = 
so now we we will make the two parts to be whole number
first factor to muliply both dividend and divisor by is looking at their decimal place as they both have two decimal places
so, that we multiplying both of them by a 10 will make them whole numbers
so so correct answer is 10
