Answer 1

Answer: -2.85

Step-by-step explanation:

To convert 22/20 into a decimal, we must multiply it by 5 to get a denominator of 100.

5(22/20)= 110/100= 1.10

So now lets solve the equation.

-1.75-1.10 = -2.85

Answer 2

-1.75 -22/20

make -1.75 and -22/20 into a mixed fraction

-1 75/= -1 75/100 ( divide by 5 for the numerator and denominator)

75/5=15

100/5=20

Divide 15 and 20 again ( reducing)= 15/5=3, 20/5=4

-22/20=-2 2/20 ( divide by 2 for 2/20)= 2/2=1, 20/2=10

-1 3/4- 1 1/10

find the common denominator for the fractions which is 20

Multiply by 5 for -1 3/4

3(5)/4(5)=15/20= -1 15/20

Multiply by 2 for -1 1/10

1(2)/10(2)=-1 2/20

-1 15/20-1 2/20=-2 17/20 or in decimal : -2.85

Answer: -2 17/20 or -2.85
