Question

which is a run - on sentence? multiplying fractions and decimals isnt hard i can show you how. the veins in our bodies return blood to the heart.

Explanation:

A run - on sentence is a sentence that incorrectly joins two or more independent clauses without proper punctuation or conjunctions. The first sentence "Multiplying fractions and decimals isn't hard I can show you how." has two independent clauses ("Multiplying fractions and decimals isn't hard" and "I can show you how") joined without a comma and a conjunction or a semicolon. The second sentence "The veins in our bodies return blood to the heart." is a single independent clause and is a correct sentence. So the run - on sentence is the first one: "Multiplying fractions and decimals isn't hard I can show you how."

Answer:

Multiplying fractions and decimals isn't hard I can show you how.
