Akshara sold 3 5 of her cupcakes and had 350 cupcakes left how many cupcakes did she sell?

She sold 350 cupcakes - 3/5 * 350 cupcakes = 350 cupcakes - 3 * 70 cupcakes = 350 cupcakes - 210 cupcakes = <<350-210=140>>140 cupcakes.

Akshara sold 140 cupcakes. Answer: \boxed{140}.

To find out how many cupcakes Akshara sold, we can subtract the number of cupcakes she had left from the total number of cupcakes she initially had.

Let's denote the total number of cupcakes Akshara initially had as 'x'.

According to the given information, Akshara sold 3/5 of her cupcakes, which means 3/5*x.

We also know that she had 350 cupcakes left. So we can write the equation:

x - 3/5*x = 350

To solve for x, we need to find a common denominator for the fractions. In this case, it is 5.

Multiplying the numerator and denominator of 3/5 by 5, we have:

5/5*x - 3/5*x = 350

Now we can combine the like terms:

2/5*x = 350

To isolate x, we need to divide both sides of the equation by 2/5:

x = 350 / (2/5)

To divide by a fraction, we can multiply by its reciprocal:

x = 350 * (5/2)

x = 1750 / 2

x = 875

Therefore, Akshara initially had 875 cupcakes and she sold:

3/5 * 875 = 525 cupcakes.

To find out how many cupcakes Akshara sold, you need to subtract the number of cupcakes she had left from the total number of cupcakes she originally had.

Let's denote the total number of cupcakes Akshara originally had as X.

According to the given information, she had 350 cupcakes left. So, the equation would be:

X - 350 = cupcakes sold

Therefore, the number of cupcakes Akshara sold would be X - 350.
