One way working this out is to find all the numbers that go into 90 by listing all the pairs of numbers that multiply to give 90
1 × 90
2 × 45
3 × 30
6 × 15
9 × 10
From here we can do trial and error:
Let's choose any two factors, say 2 and 3
By listing their multiples, we will find their LCM is 6, not 90
Then choose any two factors, say 3 and 6
By listing their multiples, we will find their LCM is 6, not 90
We can try some bigger number, say 45 and 90
by listing their multiples, we will find their LCM 90
Answer: 45 and 90

Answer:
4 1/2 days
Step-by-step explanation:
The time is given by ...
time = quantity/rate
time = (3/4 fence)/(1/6 fence/day) = (3/4)(6) days = 4 1/2 days
the question in the attached figure
we know that
Right triangles PBM and MTF are similar
because
angle PMB=angle TMF
and
angle BPM=angle FTM
and
angle B =angle F=90 degrees
so
corresponding sides are
BM and MF
PB and TF
PM and MT
(PB/TF)=BM/MF
solve for PB
PB=(TF*BM)/MF
where
TF=6ft
BM=20 ft
MF=3 ft
so
PB=(6*20)/3------> 40 ft
the answer is
the height of the peak is 40 ft
Answer:
1 lbs=$7.90
Step-by-step explanation:
To solve this problem we need to use a proportion
to solve the proportion we would divide 1,477.38 by 187 which is 7.9 so the price per pound is 7.9
