Put in order least to greatest , 9/10 5/25 49/50 6/100

6/100, 1/5, 9/10, 49/50

Step-by-step explanation:

Convert them all to decimals by dividing the numerator by the denominator.

9/10 = 0.9

5/25 = 0.2

49/50 = 0.98

6/100 = 0.06

Now, place them in order from least to greatest which is:

0.06, 0.2, 0.9, 0.98

a.k.a

6/100, 1/5, 9/10, 49/50

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:

answer

a,b, and d

explanation

a reflection angle is more than

but less than;

an angle that measures

is a reflex angle.(true)

an angle that measures less than

is acute.(true)

provided we are considering angles greater or equal to zero.

an acute angle lies in the range.

an obtuse angle is less than 180° but more than 90°

an angle that measures 300° is obtuse (false)

an angle that measures 65° is an acute angle.(true)
