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

40x7=28x10
280=280
they are equivalent which means our ratio is correct :)

Answer: B. 17</h3>
The mode is the most frequent or most occurring value. The value 17 shows up the most times, at two times, so this is the mode. The value 19 is not even part of the given set of values, so you can immediately cross of choice A.
Side note: it is possible for a set to have more than one mode, and it's also possible to not have a mode at all.

Step-by-step explanation:
3.2(4p + 8.5)

Answer:
40 years old
Step-by-step explanation:
Let's imagine a+b=63
63-12=51 (since they were both 6 years younger)
A is double B
34+17=51
34/2=17
You need to add the 6 years back onto the mothers age - 34+6=40
