Answer:
The percent increase in iron = 50 %
Step-by-step explanation:
Initial amount of iron per serving = 1.2 mg
After an increase the amount of iron per serving = 1.8 mg
Increase in the amount of iron per serving = 1.8 - 1.2 = 0.6 mg
Percent increase in iron is calculated as
Put the values in above formula we get
= 50 %
Therefore the percent increase in iron = 50 %
if you've read those links already, you'd know what we're doing here.
we'll move the repeating part to the left-side of the dot, by multiplying by "1" and as many zeros as needed, or 10 at some power pretty much.

From the prime factorization of 49, we get 7*7. From 196, we get <span>2*2*7*7. From 343, we get 7*7*7. The greatest "overlap" or common factors are 7*7, or 49.</span>
Thus, the greatest common factor is 49.
