Which is the quotient of 11/12 divided 5/7
Jet001 [13]
The answer is 77/60. 

When dividing 2 fractions the way I learned was to multiply the first fraction with the reciprocal of the second number. 

so it would be 11/12 x 7/5 

and when you multiply that you get 77/60

Hope I helped!

Tiles in this image would cover a 1 ft.? area of the kitchen. The large tiles cost $0.96 each and the small tiles cost $0.26 eac
Mice21 [21]

Answer:

B. $264.00

Step-by-step explanation:

==>The image that shows the pattern of the arrangement of tiles consists of:

2 large tiles = $0.96*2 = $1.92

8 small tiles = $0.26*8 = $2.08

This implies that $4 would need to be spent to cover 1ft²

Therefore, to cover an area of 22ft by 3ft, it would cost Fred the following below:

Area to be covered = 22×3 = 66ft²

$4 --> 1ft²

x$ ---> 66ft²

= (66 × 4)/1

= $264.00
