Hey there! A dozen rolls = 12 rolls, of means multiply, we are going to multipy 3/4 by 12, make 12 a fraction, 12=12/1. Now, we can multiply 3/4 by 12/1. 3/4×12/1=36/4. Simplify 36/4 to 9. So, Raymond bought 9 rolls.
Answer:
4
Step-by-step explanation:
The girls are 4/9 of the total number of boys and girls, so the total number is 9×96/4=216 and there are 5/9×216=120 boys.
Let the extra number of boys be b, then the total becomes 216+b. We have 96 girls and 120+b boys.
The ratio 2/3=96/(120+b).
Cross multiplying: 2(120+b)=3×96=288.
240+2b=288, 2b=288-240=48, b=24.
So 24 boys arrived.
Answer:The whole numbers are the numbers 0, 1, 2, 3, 4, and so on (the natural numbers and zero). Negative numbers are not considered "whole numbers." All natural numbers are whole numbers, but not all whole numbers are natural numbers since zero is a whole number but not a natural number.
