Answer:
505.85
Step-by-step explanation:
Because 33.5 × 15.1 is 505.85.
200 birds - 120 females = 80 males
80 males ÷ 200 birds = 0.4
0.4 × 100 = 40%
The difference (the answer of a subtraction problem) is:
2/7 - 2/5 --> 10/35 - 14/35 = -4/35
The answer sum (the answer of an addition problem) is:
2/7 + 2/5 --> 10/35 + 14/35 = 24/35
Hope this helps.
K:A
5:3 (before)
15:9
since the total number of stamps didn't change, the total ratio should be the same.
7:5(after)
14:10
so this means 1 unit is 10stamps.
14-10=4
4 X 10= 40
