Zoe and Hannah share tips in the ratio 3:7. Last week, Zoe received £24. How much did Hannah receive last week?​
frozen [14]

Answer:

56

Step-by-step explanation:

If the ratio of Zoe; Hannah is 3:7 and Zoe got 24 than we have to divide the 24 by 3 so we can multiply it by 7. This is because since the Zoe is the 3 and it isn't a 1 it isn't the starting point for either of the ratios we cannot multiply the 24 by 7.

24 ÷ 3 = 8

Now we multiply the 8 by 7 so that we know have many tips Hannah made

8 × 7 = 56

Hannah made 56 in tips

Combine like terms to create an equivalent expression.<br><br> 17−3(37n−27)71 −3( 73 n− 72)
patriot [66]

Answer:

\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})=1-\frac{9}{7}n

Step-by-step explanation:

Given : Expression \frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})

To find : Combine like terms to create an equivalent expression ?

Solution :

Step 1 - Write the expression,

\frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})

Step 2 - Apply distributive property, a(b+c)=ab+ac

=\frac{1}{7}-3\times \frac{3}{7}n+3\times \frac{2}{7}

=\frac{1}{7}-\frac{9}{7}n+\frac{6}{7}

Step 3 - Combine like terms,

=\frac{1}{7}+\frac{6}{7}-\frac{9}{7}n

=\frac{1+6}{7}-\frac{9}{7}n

=\frac{7}{7}-\frac{9}{7}n

=1-\frac{9}{7}n

Therefore,  \frac{1}{7}-3(\frac{3}{7}n-\frac{2}{7})=1-\frac{9}{7}n
