  3740

Given:

The expression, 45+18.

Concept Used:

Step 1: Find the least common multiple (LCM) for the denominators.

Step 2: Multiply the numerator and denominator to get like denominators.

Step 3: Turn the other fractions into equivalent fractions.

Step 4: Add the numerators over the common denominator.

Step 5: Simplify and reduce the answer if necessary.

Calculation:

In order to simplify the given expression, note that the least common multiple of 5 and 8 is 40. So, make both denominators equal to the LCM and combine the numerators of the common LCM to simplify further as shown below

  45+18=4588+1855=3240+540=32+540=3740

Thus, the simplified expression is 3740 .
