Answer:

\frac{3}{10}

Step-by-step explanation:

First we have to make the fractions even so there denominator have to be equal. So 15 times 2 gets 30 and 6 times 5 gets 30 too. Now multiply the numerator by the corresponding number of 25/30 and 16/30. Subtract to get 9/30 now simplify to get 3/10.

Answer:

<h3>Armand burnt \frac{3}{10} of wood over the winter.</h3>

Step-by-step explanation:

We know that Armand had in first place \frac{5}{6}.

Then, at the end of the winter, he had \frac{8}{15}.

To know how much wood he burnt, we just have to find the difference between these two quantities

\frac{5}{6}-\frac{8}{15}=\frac{75-48}{90}=\frac{27}{90}=\frac{3}{10}

Therefore, Armand burnt \frac{3}{10} of wood over the winter.

Solise is planting 24 bushes and 16 trees in equal rows. She wants all the rows to be exactly the same with no plants left over.
ZanzabumX [31]

━━━━━━━━━━━━━━━ ♡ ━━━━━━━━━━━━━━━  

Since Solise want to plant both trees and bushes in the same number of rows, you need to find the common factor.

Since the question is asking what the greatest number of rows she can plant, you have to find the greatest common factor.

The greatest common factor of 24 and 16 is 8.

You can plant 24 bushes in 8 rows (meaning you can divide it by 8), and 16 trees in 8 rows (meaning you can divide it by 8). Since the greatest number you can divide them both by is 8, the GCF of 24 and 16 is 8.

So the greatest number of rows Solise can plant is 8 rows.

Marianna [84]

Answer:

24u + 10

Step-by-step explanation:

first rearrange the terms

4(10+6u)

4(6u+10)

then distribute the 4

4(6u) = 24u

4(10) = 10

then you get 24u + 10
