Answer:

i guess as a decimal it might be
.50 to .75 but dont take my word for it
Step-by-step explanation:
10 into 5 is 2
15 into 5 is 3
237
if I have my calculations right it would be £120
780
B.) 10 cm squared
y = 2 / (r/3 - s/5)
r/3 - 2/y = s/5
add 2/y to both sides
r/3 = s/5 + 2/y
Subtract s/5 from both sides
r/3 - s/5 = 2/y
multiply both sides by y
y(r/3 - s/5) = 2
Divide both sides by r/3 - s/5
