The first, third and fourth terms of a proportion are 56, 49 and 70 respectively. Find the second term.
To find the second term of the proportion, we can set up a proportion equation using the given information.
A proportion equation states that if you have two ratios that are equal, then their products are also equal.
Let's denote the second term as x. Then we can set up the proportion equation:
(56/49) = (x/70)
To solve for x, we can use the property of cross multiplication.
Cross multiplication states that the product of the means is equal to the product of the extremes.
So, we can set up the equation:
56 * 70 = 49 * x
Simplifying, we get:
3920 = 49x
Dividing both sides by 49:
3920/49 = x
x = 80
Therefore, the second term of the proportion is 80.
56/x = 49/70
solve for x
