300x3=900
300 divided by 5 (0.2 as a fraction 1/5) is 60
60x8=480
900-480=420
Mrs Jenkins would give £420 to charity
hope this helps :)
4/10= 0.4
So if 0.4x10=4, That means that 4. Is 4/10 of 10.
Perimeter of any figure is all its sides summed up
for a rectangle, with two equal pairs, that means, length + length + width + width or 2length + 2width, or 2(length + width)
but we know the length is 7/5 the width
width = w
perimeter = P

and the length is 7/5 of that
Answer:
13.35
Step-by-step explanation:
you multiply 89 times 15
then divide that with 100
Answer:
no
Step-by-step explanation:
If you mean
27^4 - 9^5·3^9 = -1161730026
it has no factors of 5, so cannot be divisible by 25.

If you mean ...
(27^4 -9^5)/3^9 = ((3^3)^4 -(3^2)^5)/3^9 = 3^10(3^2 -1)/3^9 = 3(9-1) = 24
it is not divisible by 25, either.
