Question

e) Patient A weighs 135.8 pounds. Patient B weighs 135 2/5 lbs. Explain which patient has the greater weight, or if their weightsare equal.

Answer 1

We have the next information:

-Patient A weighs 135.8 pounds.

- Patient B weighs 135 2/5 lbs.

First, convert the weight for patient B to a decimal number.

Then:

$135\frac{2}{5}=135+\frac{2}{5}=\frac{135}{1}+\frac{2}{5}=\frac{677}{5}=135.4\text{ lb}$

We add two fractions 135/1 and 2/5:

To multiply fractions we use the next form:

$\frac{135}{1}+\frac{2}{5}=\frac{135\ast5+1\ast2}{1\ast5}=\frac{675+2}{5}=\frac{677}{5}$

Now, we need to convert 135.4 lb to pounds.

Where 1 pound = 1 lb

Hence, patient A has the greater weight.
