Answer:

36

Step-by-step explanation:

a+b=90

if a=54 then insert a back into a+b=90

54+b=90

subtract the equation by 54

54-54+b=90-54

b=36

What is the difference in length between a 11/4 inch button and a 3/8 inch button
Nutka1998 [239]

Answer:

\frac{19}{8}

Step-by-step explanation:

First, multiply the two denominators together to get the shared denominator, which will allow you to actually subtract the two numbers. 4 × 8 = 32, so the shared denominator will be 32.

Then, cross-multiply. 11 × 8 = 88, so \frac{11}{4} becomes \frac{88}{32}. 3 × 4 = 12, so \frac{3}{8} becomes \frac{12}{32}.

Now, you can subtract.  \frac{88}{32} -\frac{12}{32} =\frac{76}{32}

Finally, simplify. \frac{76}{32} =\frac{19}{8}. The final difference is \frac{19}{8}.
