I think personally it is way easier for me to do it that way. Let's say we have 6.687-4.798, then think how long it takes to solve this problem versus just solving 6.700-4.800. Does that make sense?

Estimation is a important skill to know when adding and subtracting decimals because if you estimate you have an idea on what your answer should be close to.

For example 4.68-2.38 could be 5-2 which is 3. 4.68-2.38 equals 2.3. 2.3 is close to 3.

This question is confusing. Please help me!
patriot [66]

Answer:

C. 490.

Step-by-step explanation:

25% = 0.25.

If the number of emails that Ryan and Taylor each received  is x emails then Sara received  2x + 0.25 * 2x = 2.5 emails.

So 2x + 2.5x = 882

x = 882/4.5

x = 196.

So Sara received 2.5 * 196

= 490 emails.
