Katyanochek1 [597]

Answer:

a = 11/12

Step-by-step explanation:

1/3 + a =5/4

Subtract 1/3 from each side

1/3-1/3 + a =5/4-1/3

a = 5/4 -1/3

Get a common denominator of 12

a = 15/12 - 4/12

a = 11/12

One serving of this cereal provides you with 160 mg of sodium. This is 7% of your body's daily needs. How many milligrams of sod
denis23 [38]
First, we see the closest multiple of 7 under 100 is 98 and that divided by 7 is 14. there are 2/7 as our remainder. We do 2/7 times 160 to get 320/7 and 320/7 = 45 and 5/7. We convert 5/7 into a decimal like 5/7 = .7. The answer is 45.7 milligrams of sodium.
