Answers

Answer 1

Answer: If you would like to know which pair of measurements is not equivalent, you can calculate this using the following steps:

1 lb = 16 oz
1 ton = 2,000 lb

4 lb = 4 * 16 oz = 64 oz
3 tons = 3 * 2,000 lb = 6,000 lb
8 lb = 8 * 16 oz = 128 oz
5 tons = 5 * 2,000 lb = 10,000 lb

Not equivalent: 108 oz., 8 lb.

25.83 is 52.5% of what number

Answers

The question asks to find the unknown number - x and we know that 25.83 represents 52.5% of that number. 52.5 % = 0.525. We can make an equation: 0.525 * x = 25.83, where x is the required number. x = 25.83 : 0.525, x = 49.2. Also we can say that x is 100% and 25.83 is 52.5%. Therefore: x : 25.83 = 100 : 52.5; 52.5 x = 100 * 25.83; 52.5 x = 2583; x = 2583 : 52.5; x = 49.2. Answer: the required number is 49.2.
