Math Problem Statement

127. Find the number that fits into the following multiplication equations: a) 6 × * */* */* 7 b) * × 8 */* */* 7 128. How many characters in this product are the same at the end? 1 × 2 × 3 × 4 × ... × 9 × 10 129. Find the number to fit the following multiplication setup: 11 × 6 */* 8 */* 6 */* 4 */* 2

Solution

This is a set of math problems related to multiplication and number patterns. Let's break down each question:

127. Find the number that fits into the following multiplication equations:

a)

\frac{*}{*} \\ \frac{*}{*} 7$$ b) $$* \times 8 \\ \frac{*}{*} \\ \frac{*}{*} 7$$ These seem to be multiplication problems where some numbers or symbols are missing, and the task is to identify the appropriate value to complete the equation. ### 128. How many characters in this product are the same at the end? $$1 \times 2 \times 3 \times 4 \times \cdots \times 9 \times 10$$ This problem is asking how many of the digits in the result of multiplying the numbers 1 through 10 are the same at the end. ### 129. Find the number to fit the following multiplication setup: $$11 \times 6 \\ \frac{*}{*} 8 \\ \frac{*}{*} 6 \\ \frac{*}{*} 4 \\ \frac{*}{*} 2$$ It looks like a multiplication structure where the missing numbers need to be determined. I can help solve these problems step by step. Would you like me to start with the first question, or would you prefer to address any specific part? Feel free to clarify any missing details. --- ### Further Related Questions: 1. How do you solve multiplication puzzles with missing numbers? 2.
