Question

4\15+7\30+4\15+7\30+4\15+7\30+4\15+7\30=

Answer 1

4\15+7\30+4\15+7\30+4\15+7\30+4\15+7\30=4\15 *4+7\30*4=

=4*(4\15+7\30)=4*(8\30+7\30)=4*(8+7)\30=4*15\30=4*1\2=2

Answer 2

To solve the expression 4/15 + 7/30 + 4/15 + 7/30 + 4/15 + 7/30 + 4/15 + 7/30, we can follow these steps:

Step 1: Find the common denominator The denominators in this expression are 15 and 30. The least common multiple (LCM) of 15 and 30 is 30. So we can rewrite the expression with a common denominator of 30:

(4/15) + (7/30) + (4/15) + (7/30) + (4/15) + (7/30) + (4/15) + (7/30)

Step 2: Convert fractions to have the same denominator To convert the fractions, we need to multiply the numerator and denominator of each fraction by the same value so that the denominator becomes 30:

(4/15) * (2/2) + (7/30) + (4/15) * (2/2) + (7/30) + (4/15) * (2/2) + (7/30) + (4/15) * (2/2) + (7/30)

This simplifies to:

(8/30) + (7/30) + (8/30) + (7/30) + (8/30) + (7/30) + (8/30) + (7/30)

Step 3: Add the fractions Now that all the fractions have the same denominator, we can add them together:

(8/30) + (7/30) + (8/30) + (7/30) + (8/30) + (7/30) + (8/30) + (7/30) = 57/30

So, the expression 4/15 + 7/30 + 4/15 + 7/30 + 4/15 + 7/30 + 4/15 + 7/30 is equal to 57/30.
