namely, how many times does 2/7 go into 7/8?
So we don't know both of their age but we do know that Jessica is 4 year younger so let make x stand for Jennifer age and n is for jessica so our equation needs to be n + 10 = 8 + 2n subtract n from both sides so now we have 10 = 8 + n then subtract 8 from both sides so now we have 10 - 8 = n so jessica is 2 but now we need to find Jennifer age by adding 4 to 2 = 6
jessica is 2 and Jennifer is 6
Last question of a really important test! I really need some help!

Answer:
4090 ml - 4.9L
1.4km - 4901m
Step-by-step explanation:
A liter is made up of 1000 ml so 4.9 l is equvilant to 4,900 ml.
A kilometre same as litre is made up of a 1000 m. So 1.4 km is 1400m
However, ml and l is a measurement of volume while m and km is a measurement of distance.
