Question

Jared needs 2.4 micrograms of vitamin B-12 each day. Today, Jared drank a serving of milk containing 0.44 micrograms of B-12 and ate a lamb chop containing 1.224 micrograms of B-12. Which method can Jared use to find the number of micrograms of vitamin B-12 he still needs?

Answer 1

He can use addition by adding 0.44 and 1.224 together to see how much Vitamin B-12 (so far he has 1.664 in all.) he has right now. then he needs to subtract that amount (1.664) of B-12 he has from the amount of vitamin B-12 (2.4) he needs. That'll be 0.736 of vitamin B-12 he needs to reach the amount of B-12 he needs.

Answer 2

Answer:

0.736 micro grams.

Step-by-step explanation:

Jared needs 2.4 micro grams of vitamin B-12 each day.

Today, Jared drank a serving of milk containing = 0.44 micro grams of B-12

and he ate a lamb chop containing = 1.224 micro grams of B-12

Total consumption of  B-12 = 0.44 + 1.224 = 1.664 micro grams

To find the number of micro grams of vitamin B-12 he can use the method

He still need = Need B-12 (micro grams)  - consume B-12(micro grams)

He still need = 2.4 - 1.664 = 0.736 micro grams.

Jared still needs 0.736 micro grams vitamin B-12.
