Semmy [17]

Answer:

Total = \frac{1}{2}

Step-by-step explanation:

Given

Carol = \frac{1}{8}

Luke = \frac{3}{8}

Required

How far did they row together

To do this, we simply add the distance they both covered.

Total = Carol + Luke

This gives;

Total = \frac{1}{8} + \frac{3}{8}

Take LCM

Total = \frac{1+3}{8}

Total = \frac{4}{8}

Simplify

Total = \frac{1}{2}

<em>Hence, they both rowed 1/2 mile</em>

Sheldon harvests the strawberries and tomatoes in his garden. He picks 1 2/5 kg less strawberries in the morning than in the aft
Natalija [7]

Let

x ----> kilograms of strawberries that Sheldon picks in the morning

y ---> kilograms of strawberries that Sheldon picks in the afternoon

so

we have that

x=y-1 2/5

x=2 1/4 kg

substitute

2 1/4=y-1 2/5

Convert mixed numbers to an improper fraction

1 2/5=1+2/5=7/5

2 1/4=2+1/4=9/4

substitute

9/4=y-7/5

y=(9/4)+(7/5)

y=(45+28)/20

y=73/20 kg

Adds kilograms in the morning and afternoon

x+y=(9/4)+73/20)

x+y=(45/20)+(73/20)

x+y=118/20 kg

Convert to mixed number

118/20=100/20+18/20=5+18/20=5+9/10=5 9/10 kg

therefore

<h2>The answer is 5 9/10 kg</h2>
