Answer:
The problems with same answers are:
(a, 4), (b, 3), (c, 1), (d, 5) and (e, 2).
Step-by-step explanation:
The two sets of problem are as follows:
<u> Set 1 </u> <u> Set 2 </u>
a. 36·4+36·9 1. (8+2)·19
b. 17·(18−15) 2. 11·(14+6)
c. 8·19+2·19 3. 17·18−17·15
d. (26−18)·6 4. 36·(4+9)
e. 11·14+11·6 5. 26·6−18·6
The matched pairs are as follows:
<u>a</u>. 36·4+36·9 = 36·(4 + 9) → <u>4</u>. 36·(4+9)
<u>b</u>.17·(18−15) = 17·18−17·15 → <u>3</u>. 17·18−17·15
<u>c</u>. 8·19+2·19 = (8 + 2)·19 → <u>1</u>. (8+2)·19
<u>d</u>. (26−18)·6 = 26·6−18·6 → <u>5</u>. 26·6−18·6
<u>e</u>. 11·14+11·6 = 11·(14+6) → <u>2</u>. 11·(14+6)
Thus, the problems with same answers are:
(a, 4), (b, 3), (c, 1), (d, 5) and (e, 2).
