On Monday, Luis ran 1 ¼ of a mile. On Tuesday, he ran 2 1/3 of a mile. How many miles did he run in all? I need help pls.

3 7/12

Explanation:

1 1/4 x 3 = 1 3/12

2 1/3 x 4 = 2 4/12

3/12 + 4/12 = 7/12

1 + 2 = 3

3 7/12

- "a nonrestrictive clause functions as a modifier to a noun (that is an object, person or concept). these clauses can be described by the following three options: it is set off by comas, it contains a subject and a verbs and it adds nonessential information to the sentence.

for example, in "here is bill gates, who confounded microsoft software company" we can identify "who confounded microsoft software company" as a nonrestrictive clause modifying the noun bill gates. this clause can be describes as a nonrestrictive clause because it is separated by a comma, it adds nonessential information to identify who bill gates is and it must contain both a subject (who) and a verb (confounded)."
