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(2)/(5)=135+(2)/(5)=(135)/(1)+(2)/(5)=(677)/(5)=135.4\text{ lb}`

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

To multiply fractions we use the next form:

`(135)/(1)+(2)/(5)=(135\ast5+1\ast2)/(1\ast5)=(675+2)/(5)=(677)/(5)`

Now, we need to convert 135.4 lb to pounds.

Where 1 pound = 1 lb

Hence, patient A has the greater weight.
