write a decimal and 45/90 in simplest form

45/90 = 1/2 = 0.5

45/90=45/(2*45)=1/2=0.5

45/90=1/2=0.5

To write a decimal and 45/90 in simplest form, we need to simplify the fraction first.

To do this, we find the greatest common divisor (GCD) of the numerator (45) and the denominator (90). In this case, the GCD of 45 and 90 is 45, since both numbers are divisible by 45.

To simplify the fraction, we divide both the numerator and denominator by the GCD:

45 ÷ 45 = 1
90 ÷ 45 = 2

Therefore, 45/90 simplified to its simplest form is 1/2.

To write it as a decimal, we divide the numerator (1) by the denominator (2), using long division.

1 ÷ 2 = 0.5

So, the decimal and 45/90 in simplest form is 0.5 or 1/2.
