Pls so easy will give !

1.reduce -56/-70 to lowest terms.

a. 8/10
b. - 4/5
c. - 2/3
d. 4/5

2.reduce -34/87 to lowest terms.

a. - 2/5
b. - 1/3
c. - 11/29
d. it is already reduced.

3.what is the gcf of the numerator and denominator in the following fraction? 21m^2n/28mn^2

Step-by-step explanation:

-56/-70=56/70=4/5

The answer is D.

-34/87=-34/87

D) It's already simplified.

The GCF is 7mn.

answer:

total cost for tiles and paints is $924.  

step-by-step explanation:

we have been given that a community hall is in the shape of a cuboid. the hall is 40m long 15m high and 3m wide.

the paint will be required for 4 walls and ceiling.

let us find area of walls and ceiling.

therefore, the area of walls and ceiling is 1410 square meters.

given: cost for 10 litre of paint is $10 and 10 litre paint covers 25 square meter. therefore,

therefore, the total painting cost is $564.

tiles will be required for floor. let us find the area of floor.

given: 1m squared floor tiles costs $3. so,

therefore, the total tiles cost is $360.

now let us find combined total cost of tiles and paint.

therefore, the combined total cost of tiles and paint is $924.
