Question

if a is 40% of b, then b exceeds a by what percent of a?

Answer 1

please give explanations too , please

Answer 2

a is 40% of b so.. \[a = \frac{40}{100} \times b\]

Answer 3

yes i got that far

Answer 4

wait..im thinking this through too :D

Answer 5

so \[b = \frac{100}{40}\times a\]

Answer 6

whyd you flip it? :0

Answer 7

i multiplied both sides by 100/40 to get rid of 40/100 on the right side

does that make sense?

Answer 8

OHH i see it

Answer 9

\[b = \frac{40 + 60}{40} \times a\]
do you see this too?

Answer 10

hmm can you explain

Answer 11

i just broke 100 into 40 + 60

Answer 12

oh haha

Answer 13

because of this
\[b = (\frac{40}{40} + \frac{60}{40} ) \times a\]

Answer 14

still seeing it?

Answer 15

yes

Answer 16

\[b = (1 + \frac 32) a\]
what about this?

Answer 17

yup

Answer 18

im pretty sure you see this too
\[b = a+ \frac 32 a\]

Answer 19

kkkk

Answer 20

next would be
\[b = a + \frac{3\times 50}{2 \times 50} a\]
\[b = a + \frac{150}{100} a\]
so b exceeds a by 150% of a i guess..
