▼

To find out how much pizza Alejandra and Ernesto ate together, we need to add their fractions: 2/12 + 4/6.

First, we must find a common denominator. The denominators are 12 and 6. The least common multiple of 12 and 6 is 12.

Convert 4/6 to a fraction with a denominator of 12:
4/6 = (4 × 2) / (6 × 2) = 8/12

Now add the fractions:
2/12 + 8/12 = 10/12

Simplify 10/12 by dividing both numerator and denominator by their greatest common divisor, which is 2:
10 ÷ 2 = 5
12 ÷ 2 = 6

So, 10/12 simplifies to 5/6.

The answer is 5/6.
