Unsure of what you're asking by "<span>What is the rate of 2.50/10.50
and 1.99/2.50?" Do you mean, "</span><span>What is the RATIO of 2.50/10.50
and 1.99/2.50?"
If so, this ratio is
2.5/10.5
---------------
1.99/2.50
Invert the denominator, obtaining 2.50/1.99, and then multiply the numerator 2.5/10.5 by this result:
2.5 2.5 6.25
------- * ------- = ----------- = 1 / 3.3432, or 0.2991.
10.5 1.99 20.895

What is an equation?</h3>
- An equation is a formula in mathematics that expresses the equality of two expressions by connecting them with the equals sign =.
- The word equation and its cognates in other languages may have subtly different meanings; for example, in French, an équation is defined as containing one or more variables, whereas in English, an equation is any well-formed formula consisting of two expressions linked by an equals sign.
To find the value of t:
Given -
- (t+5)/(t-5) = 10
- t+5 = 10(t-5)
- t+5 = 10t - 50
- 10t - t = 5 + 55
- 9t = 55
- t = 55/9
Therefore, the value of t is (D) 55/9.
