Answer:
25 ma'am
Step-by-step explanation:
Daniel rowed 1/2 mile
Annabelle rowed 1/4 mile
Part A:
Did Laura row a distance greater than, less than, or equal to the combined distance of Daniel and Annabelle?
We can make everything have the same denominator so we can add, subtract, and compare them:
The common denominator between 2, 4, and 8, is 8.
7/8 = 7/8
1/2 = 4/8
1/4 = 2/8
The question is if Laura rowed more, less, or the same to the combined distance of Daniel and Annabelle:
Laura : 7/8
Daniel: 4/8
Annabelle: 2/8
4/8 + 2/8 = 6/8
So Daniel and Annabelle's distance combined is 6/8, which is less than Laura's:
7/8 > 6/8.
This means that Laura rowed more than Daniel and Annabelle.
