Hey there! :)
Let's change all the fractions and percents to decimal.
_____________________________________________________________
When changing fractions to decimal, divide the numerator by the denominator
When changing percents to decimal, remove the % sign and move the decimal to places to the left.
_____________________________________________________________
13 ÷ 20 = 0.65
66% = 0.66
195 ÷ 300 = 0.65
0.6500 = 0.65
_____________________________________________________________
The answer is 66% because it is the only one that isn't equivalent to 0.65
Hope this helps :)
Answer:
31.04%
Step-by-step explanation:
So he increased 17%, then increased 12%.
When he increased by 17%, his height was 117%, relative to his former height. 12% of 117% is 14.04%
So he increase 17%, then increased 14.04% ( of his original height) so his total growth was 31.04%
Answer:
y=4x
Step-by-step explanation:
it's enough to use first column (x=6, y=24). Inserting this data into equation y=kx, we can calculate k.
24=k*6
6k = 24
k = 24/6
k = 4
Make them all have the same denominator
32
25+12 16/32+488/32+124/32+38/32+25/32
Add all of the numerators... to get 691/32+1184/32
1875/32
Simplify to get 58 19/32
