−12+6
Step-by-step explanation:
Answer:
0.5:1
Step-by-step explanation:
laps:minutes
So we can find how much Ronald runs in 2 minutes, by dividing 6:12 (or 6/12) by 6. This will give you 1:2 (One lap = 2 minutes).
But you're looking for 1 minute, so with 1:2, you have to divide them by 1/2, so it will be 0.5:1.
8 16/1000 = 8 2/125
Keep whole number the same, divide the numerator and denominator by 8.
3×15=15
4×7=28
The only multiple of 10 between these two numbers is 20. 20 does indeed have factors that are odd or even so we can conclude that 20 must be the answer.
Answer:
Here c represents the total number of children in choir.
As per the statement:
Total number of boys in choir = 12
It is also given that: Three sevenths of a children's choir are boys.
⇒ Total number of boys = 
or

By cross multiply we have;
84 = 3c
Divide both sides by 3 we have;
c = 28
Therefore, the total number of children in choir is 28 children
