Step-by-step explanation:
<u>Given:</u>
2/20 : 1/40
A). First re-write the ratio as follows;
(i) Change the ratio sign to division (÷). i.e
2/20 ÷ 1/40
(ii) Solve the expression by changing the division to multiplication(×). This also means you will need to swap the numerator and the denominator of the second term. i.e (1 / 40) becomes (40 / 1)
(2/20) × (40 / 1) = × =
B). Now convert the result from above to unit rate. A unit rate is a rate in which the denominator has a value of 1.
So to convert to unit rate, we keep simplifying until the denominator becomes 1.
And since the denominator is already 1, there is no need for further simplification.
Therefore, 2/20 : 1/40 to unit rate is
Answer:
Answer is 6/10 and 12/20
Step-by-step explanation:
Let the numerator be x.
3/5=x/10
x=30/5
x=6
The required fraction is 6/10
Now same method applies for taking 20 as denominator
3/5=x/20
x=60/5
x=12
The required fraction is 12/20
Answer: (x,y) (-y,x)
Step-by-step explanation:
Measure of all angles in a triangle is 180
180-100=80
Middle angle plus smallest angle =80
smallest angle(s) +24=middle angle(m)
s+s+24=80
2s+24=80
2s+24-24=80-24
2s=56
2s/2=56/2
s=28
m=28+24
m=52
smallest angle is 28
middle angle is 52
100+28+52=180
