Tap to see back →
First, convert $\frac{1}{4}$ into a decimal. We are left with
.24+2.5+.25
Now add the three numbers, being careful to line the decimal points up exactly. From right to left we will add:
-
4 and 5 = 9
-
5, 2, and 2 = 9
-
2 is alone = 2
This leaves us with 2.99 for the final answer.

In a math contest, the team from Lincoln High comprised five students - Melanie, Ned, Olivia, Phyllis, and Quinn. Melanie outscored Ned by 12 points; Ned outscored Quinn by 19 points; Phyllis outscored Ned by 45 points and Olivia by 20 points. Who came in third among the five?

Since this reasoning is valid regardless of the actual scores, suppose Quinn scored 100. Then Ned scored 19 more than Quinn, or 119, and Melanie scored 12 more than Ned, or 131. Phyllis scored 45 more than Ned, or 164, and Olivia scored 20 points fewer than Phyllis, or 144. This makes the order, from greatest to least:
Phyllis, Olivia, Melanie, Ned, Quinn
Melanie scored third among the five.
