A is the answer. it’s the answer
Find the answer for 15:
462,371 * 10 = 4,623,710
(millions place)
Find the answer for 16:
How many hundreds to make a thousand?
10! because 371 * 10 = 3,710
(10 times)
Step-by-step explanation:

e.g.

Answer:
6 L
Step-by-step explanation:
Given two solutions:
1st solution is 90% saline solution. Let the volume of this solution be
litres.
2nd solution is 50% saline solution. Volume of this solution = 4 L
Resultant solution is 74% saline.
To find:
The volume of 1st solution = ?
Solution:
Total volume of the 74% saline mixture = (4+
) Litres
We can write equation here, as per the percentage of saline in the mixtures.
90% of
L + 50% of 4 L = 74% of (
+4)

Therefore, the volume must be <em>6 L</em>.
