1. Round 50.75 to 50 and 0.18 to 0.20.
50 x 0.2 = 10
2) Round 96 to 100 and 0.499 to 0.5
100 divided by 0.5 = 50
3a) Round 8.2 to 8, 6.7 to 7, and 0.46 to 0.50
8 x 7 divided by 0.50 = 112
3b) Round 23.4 to 20, 13.9 to 10, and 0.18 to 0.20
20 x 10 divided by 0.20 = 2,000
7/16 is proportional to 35/80 also 14/32 , 21/48 and 28/64 and an infinite number of possibilities

Answer:
20% decrease
Step-by-step explanation:
First, let's find the net decrease: Peter started at 80kg and his weight is now 64kg, which is a 16kg decrease. Next, we need to find what percentage of 80kg 16kg represents. First, let's find what part of 80 is 16:
16/80 = 1/5
To convert this to a percent, we need to find an equivalent fraction to 1/5 with a denominator of 100. To do this, we can multiply the numerator and denominator of 1/5 by 20, giving us 20/100, or 20%.
