Question

12/19×23/15-12/19×4/15

Answer 1

Ответ будет 4/5
..........

Answer 2

12/19  ×  23/15  -  12/19  ×  4/15 = 92/95  -  12/19  ×  4/15 = 92/95  -  16/95 =  76/95 = 4/5

Answer 3

I can help you with math problems. Here is the detailed solution for your question:

The given expression is $$\frac{12}{19} \times \frac{23}{15} - \frac{12}{19} \times \frac{4}{15}$$

To simplify it, we can use the distributive property of multiplication over subtraction. That is, $$a \times (b - c) = a \times b - a \times c$$

So, we can rewrite the expression as $$\frac{12}{19} \times \left(\frac{23}{15} - \frac{4}{15}\right)$$

Next, we can subtract the fractions inside the parentheses by finding the common denominator and subtracting the numerators. The common denominator is 15, so we have $$\frac{23}{15} - \frac{4}{15} = \frac{23 - 4}{15} = \frac{19}{15}$$

Now, we can multiply the fractions by multiplying the numerators and the denominators. We have $$\frac{12}{19} \times \frac{19}{15} = \frac{12 \times 19}{19 \times 15} = \frac{228}{285}$$

Finally, we can simplify the fraction by dividing both the numerator and the denominator by the greatest common factor (GCF). The GCF of 228 and 285 is 3, so we have $$\frac{228}{285} = \frac{228 \div 3}{285 \div 3} = \frac{76}{95}$$

Therefore, the final answer is $$\frac{76}{95}$$
