Answer:
its 273 rounded but say 270
Step-by-step explanation:
1/2 is half of a whole
whole= 1/1. 2/2, 3/3, 4/4 and so on
1/2 are numbers that can be simplify to halves= 1/2, 2/4, 3/6, 4/8, 5/10 and 1/2 are half of the denominator
1. The tables represent a ratio of 3:5. For example, 6 x 3 = 18, and 6 x 5 = 30. Also, 20 x 3 = 60, and 20 x 5 = 100.
2. The table has a ratio of 3:4, so the missing blank is 64.
Answer:
A. 16
Step-by-step explanation:
We can use a ratio to solve
4 bracelets x bracelets
----------------- = -------------
12 minutes 48 minutes
Using cross products
4 * 48 = 12x
192 = 12x
Divide by 12 on each side
192/12 =12x/12
16 =x
63/80 x 100 = 78.8%
You divide normally but multiply by 100 (moving the decimal over two places).
