HELP Which of the following is a true statement?
4/5 x 4/5=1
3/10 ÷ 7/9=3/10 x 9/7
9/12 x 12/9= 0
1/2 ÷1/2= 1/4

3/10 ÷ 7/9=3/10 x 9/7 is the true one

Step-by-step explanation:

4/5 x 4/5 = 16/25 not 1 so this statement is wrong.

3/10 ÷ 7/9=3/10 x 9/7, this is the true statement and it equals 27/70

9/12 x 12/9= 1 not 0

1/2 ÷1/2= 1 not 1/4

1/4 of a pint hope that mark as brainliest

area of rectangle a is 2 times that of rectangle b that means 2x+x =   36cm^2

3x = 36cm ^2

x = 36/3

x= 12cm^2

and 2x = 24cm^2

now side of square = are divided by sides = 36/4 = 6cm

that means length of rectangle a and b is 6cm too

now for rectangle a,

l*b = area

= 6*y=24

y=24/6 = 4

therefore dimensions of rectangle a are- length = 6cm, breadth = 4cm

and for rectangle b, length = 6cm and breadth = 6-4 = 2cm.

hope this .
