Question

I REALLY NEED HELP BUT [you need to enter your answer as a reduce fraction in the form A/b]
8/7y-2/5=1/10

Answer 1

Answer:

Step-by-step explanation:

In multiplication of fractions to multiply a fraction by one or more natural numbers ... i.e., a/b × c/d = (a × c)/(b × d) ... 8/2 = 4 (ii) 1/5 of 20 = 1/5 × 20 = 1/5 × 20/1 = 20/5 = 4 (iii) 2/5 of 25 = 2/5 × 25 ... Multiply and reduce to lowest form (if possible

Answer 2

$\frac{8}{7y} - \frac{2}{5} = \frac{1}{10} \\ \frac{4 0 - 14y}{35y} = \frac{1}{10} \\ 40 - 14y = \frac{35y}{10} \\ 10(40 - 14y) = 35y \\ 400 - 140y = 35y \\ 400 = 140y + 35y \\ 400 = 175y \\ \frac{400}{175} = y \\ y = \frac{400}{175} \\ y = \frac{16}{7}$

Answer. y = 16/7
