Answer:
a. 18
b. 45
Step-by-step explanation:
The question states that 2/5 of the class are girls which means 3/5 are boys:
Divide this value by 3 to get the value of 
:
27 ÷ 3 = 9
Multiply this by 5 to find 
, the total pupils in the class:
9 x 5 = 45
As the number of girls is 
of the total pupils:
9 x 2 = 18
So there are 18 girls in the class which has a total pupil size of 45.
Hope this helps!
If you are asking for an ecquvilent fraction it would be 9/12
Answer:
Step-by-step explanation:
Step one:
for James
the initial mile covered= 6miles
the planned number of miles per day= 3miles
let the number of days be x
and the total distance in miles be y
the total distance for the x days day will be
y=6+3x------------1
step two:
for Aaron
the planned number of miles per day= 4miles
let the number of days be x
and the total distance in miles be y
the total distance for the x days day will be
y=4x------------2
The system of equations is
y=6+3x--2
y=4x----2
Step three:
for the number of days that Aaron needs to run to meet up with James, we need to equate the two equations to find x which is the solution
6+3x=4x
6=4x-3x
x=6days
This means that Aaron will have to run at 4mile per day consistently for 6 days to meet up with James
