In a shipment of shirts to a clothing store, 2/5 of the shirts are blue and 3/10 of the shirts are red. ​If there are 20 shirts in the shipment, how many shirts are either blue or red?

14

Step-by-step explanation:

Fraction of blue shirts = 2/5

Fraction of red shirts = 3/10

Number of shirts in the shipment = 20

The number of shirts that are either blue or red will be:

= (2/5 + 3/10) × 20

= (4/10 + 3/10) × 20

= 7/10 × 20

= 14

The number of shirts that are either blue or red is 14

x = 23.78
