To solve this expression, we need to add the two terms together. However, we need to convert the decimals to fractions first: 0.3 = 3/10 0.15 = 15/100 = 3/20 Now we can add the fractions: 3/10 + 3/20 To add fractions, we need to find a common denominator. The smallest number that both 10 and 20 divide into is 20. So we need to convert the fractions to have a denominator of 20: 3/10 * 2/2 = 6/20 3/20 * 1/1 = 3/20 Now we can add the fractions: 6/20 + 3/20 = 9/20 Therefore, the expression simplifies to: 0.3р + 0.15р = 0.45р = 9/20р

To add these two expressions, we simply combine the like terms: 0.3р + 0.15р = (0.3 + 0.15)р = 0.45р Therefore, the sum of 0.3р and 0.15р is 0.45р.
