Question

tulas grandmother teaches her a wampum belt craft. she divides 172 beads equally into 4 rows to weave onto the belt. find how many beads tula puts in each row.$172\div4$what is the greatest number of tens you can put in each group?1 ten2 tens3 tens4 tens

Explanation:

Step1: Analyze the division problem

We need to solve $172 \div 4$, starting with tens place.

Step2: Break down 172 into tens

172 has 17 tens ($17 \times 10 = 170$) and 2 ones.

Step3: Divide tens by 4

$\frac{17}{4} = 4$ with a remainder of 1. So the greatest number of tens per group is 4 tens, since $4 \times 4 = 16$ tens (160) is the largest multiple of 4 tens that fits into 17 tens.

Step4: Calculate final per-row beads

First, distribute 160 beads: $\frac{160}{4} = 40$ beads. Then distribute remaining 12 beads: $\frac{12}{4} = 3$ beads. Total per row: $40 + 3 = 43$.

Answer:

• Greatest number of tens per group: 4 tens
• Number of beads in each row: 43
