To find out how many stocks went up, a proportion is set up based on the ratio provided: eight stocks rising for every nine falling. We cross-multiply and solve for x to determine that 912 stocks went up when 1026 stocks went down.
To determine how many stocks went up in the market, we need to use the given proportion of eight stocks going up for every nine stocks going down. If we know that 1026 stocks went down, we can set up a ratio like this:
Let the number of stocks that went up be x.
Set up the ratio: 8 up / 9 down = x up / 1026 down.
Cross-multiply to solve for x: 8 * 1026 = 9 * x.
Calculate: 8208 = 9x.
Divide by 9 to find x: x = 8208 / 9.
Calculate the result: x = 912 stocks went up.
Therefore, 912 stocks went up in the market.
The probable question may be:
The stock market report says that eight stocks went up for every nine stocks that went down. If 1026 stocks went down yesterday how many went up
