What is 2 and three tenths divided by 1 and seven ninths?

Answer 1

2

Answer 2

First convert the mixed numbers to improper fractions: (2+3/10)/(1+7/9)=((2*10+3)/10)/((1*9+7)/9)=(23/10)/(7/9). Division is the same as multiplying by the reciprocal:

(23/10)/(7/9)=(23/10)*(9/7). Now multiply the numbers in the numerator and the numbers in the denominator:

(23/10)*(9/7)=(23*9)/(10*7)=230/63. This is the improper fraction in simplest form. As a mixed number, this is 3 and 41/63 (since 230/63 is 3 with a remainder of 41).
