Answer:
Things like:
2/9 + 7/9 = 9/9 = 1
3/4 + 1/4 = 4/4 = 1
If the number is the same for the numerator and denominator it adds up to 1.
More examples:
6/10 + 4/10 = 10/10 = 1
9/15 + 6/15 = 15/15 = 1

Samuel drove 28 miles in 32 minutes. Beverly drove 42 miles in 48 minutes.
Are the ratios of miles to minutes for Samuel and Beverly proportional?
Drag and drop to correctly complete the statement.
= Ratio of minutes to miles in which Samuel drove = 28 : 32
= Ratio of minutes to miles in which Beverly drove = 42 : 48
To find whether the time they drove and the distance they covered were proportional or not , let us first change them into a fraction and then simplify them .
= 28 : 32 = 28/32
= 28/32
Both the numerator and the denominator is divisible by 4 .
= 28 ÷ 4 / 32 ÷ 4
= 7/8 = 7 : 8
Samuel = 7 : 8
Beverly = 42 : 48 = 42/48
= 42/48
Both the numerator and the denominator is divisible by 6 .
= 42 ÷ 6 / 48 ÷ 6
= 7/8
Therefore, the ratio of miles to minutes drove by Samuel and Beverly is proportional , 7:8 :: 7:8
Answer:
7:8 7:8
Step-by-step explanation:
if you subtract 28 from 42 and subtract 32 from 48 then you get 14-16. then double it and you get 28-32 then add 14-16 to those again and you get 42-48. because they add up and are equal, take 14-16 and simplify it to 7:8.

I need to know the missing angles
Answer:
71
Step-by-step explanation: 2x=142
x=71
Answer:
the missing angles are 71
Step-by-step explanation:
The exterior angle of a triangle is equal to the sum of the 2 opposite interior angles.
142° is an exterior angle of the triangle, thus
x + x = 142
2x = 142 ( divide both sides by 2 )
x = 71

lets start by putting our numbers into fractions then finding a like value. 35 in this case. 1/7 equals 5/35 and 1/5 equals 7/35 now we add these together and get 13/35. our next step is to flip this to 35/13 and take put any whole numbers. in this case 2 whole numbers can be made
leaving
9/13
(0.69)
converting this to minutes is 42 minutes.
