Answer:
0.65, 0.6, 0.5, 0.5
Step-by-step explanation:
There would be 35 rulers.
In order to solve this, use cross multiplication.
6/10 = 21/x -----> cross multiply
10*21 = 6*x
210 = 6x
35 = x
2L + 2W = 116
L = 2W + 10
2(2W+10) + 2W = 6W + 20 = 116
6W = 96
W = 16
L = 2W + 10
L = 2(16) + 10 = 32 + 10 = <u><em>42 cm</em></u>
You convert the fractions into 6ths. So 1/3. You would multiply both parts by 2 (top and bottom denominators) and that would be 2/6. 1/2 of 6 is 3/6. So the answer would be 1/6
