Simplify the ratio<br> 40 : 28<br> Please show work! If your able too :)
otez555 [7]

Answer:

10:7

Step-by-step explanation:

ratios are simply just like fractions!

this ratio (40:28) can be re-written as 40/28

now, you can simplify this to its lowest terms

40/28=20/14=10/7

first in those steps i re wrote the question, then divided by two, then divided by two again !

so, 40:28=10:7

--------------------------------

you can even check this by cross multiplying, since ratios are fractions

\frac{40}{28} =\frac{10}{7}

40x7=28x10

280=280

they are equivalent which means our ratio is correct :)

hope this helped <333
