Question

5) 3 2/5у=6 4/56)9 1/2=14 1/4​

Answer 1

Ответ:

3 2/5у= 6 4/5

у=6 4/5:3 2/5=34/5:17/5=34/5×5/17=2

у=2;

9 1/2у=14 1/4

у=14 1/4:9 1/2=57/4:19/2=57/4×2/19=3/2=1 1/2

у=1 1/2

Answer 2

It looks like you're trying to solve some equations involving fractions. Let's break down each equation step by step.

Equation 1: 3 2/5y = 6 4/5

To solve this equation, first, subtract 6 4/5 from both sides to isolate the term with 'y' on the left side:

3 2/5y - 6 4/5 = 0

Now, we need to convert the mixed numbers into improper fractions:

(17/5)y - (34/5) = 0

Now, let's add (34/5) to both sides to isolate 'y':

(17/5)y = (34/5)

Now, divide both sides by (17/5) to solve for 'y':

y = (34/5) / (17/5)

When you divide by a fraction, you can multiply by its reciprocal:

y = (34/5) * (5/17)

Now, simplify by canceling out common factors:

y = (2/1) * (1/17)

y = 2/17

So, the solution to the first equation is y = 2/17.

Equation 2: 9 1/2 = 14 1/4

This equation appears to be incorrect because it states that 9 1/2 is equal to 14 1/4, which is not true. There might be a mistake in the given equation. Please double-check the equation or provide additional information if there is an error or if you have another equation you'd like to solve.
