Answer: 9 / 20

Step-by-step explanation:

Convert both of the fractions to decimals and then sum them up.

= 2/10 = 0.2

= 25/100 = 0.25

= 0.2 + 0.25

= 0.45

The convert this figure back to fractions.

As it is 2 digits after the decimal, it is over 100 when converted.

= 45 / 100

Take it to the lowest term:

= 45 / 100 ÷ 5

= 9 / 20

Is 3/4 equivalent to 6/8
scoray [572]
Yes
3/4 in decimal form is 0.75
while if you divided each side (6/2 = 3 & 8/2 = 4) 6/8 = 3/4 and in decimal form it also equals 0.75

7b + 3 – 4b = 3 – 3(b + 4)
svlad2 [7]

Hello from MrBillDoesMath!

Answer:  b

Discussion:

7b + 3 - 4b = 3 - 3(b+4)  =>

7b + 3 - 4b = 3 - 3b -12 =>

(7b - 4b) + 3   = -3b - 9 =>

3b + 3 = -3b -9    =>      Add 9 to both sides

3b + 12 = -3b -9 + 9  =>

3b + 12 = -3b  =>         ( add 3b to both sides)

6b + 12 = 0 =>             (subtract 12 from both sides)

6b = -12 =>

b = -12/6 = -2


Thank you,

MrB

cedric and Gabe eat 9 pieces cake together, cedric eats 3 pieces and Gabe eats another fourth of the whole cake. How many pieces
salantis [7]

Let's assume

total number of pieces in a cake is x

Gabe eats another fourth of the whole cake

so,

Gabe eats

=\frac{1}{4} x

cedric eats 3 pieces

so,

Cedric and Gade together eat

=\frac{1}{4} x+3

we are given

Cedric and Gabe eat 9 pieces cake together

so, we can set them equal

and we get

\frac{1}{4} x+3 =9

now, we can solve for x

Subtract both sides 3

\frac{1}{4} x+3-3 =9-3

\frac{1}{4} x =6

Multiply both sides by 4

\frac{1}{4} x*4 =6*4

x =24

so,

total number of pieces are 24.........Answer
