Final answer:
The expressions 6 tens ÷ 4 tens and 6/5 ÷ 4/5 are similar because they involve division between the same value, which is 6. The result in both cases is 1.5.
Step-by-step explanation:
In both expressions, 6 tens ÷ 4 tens and 6/5 ÷ 4/5, the division is happening between the same value, which is 6.
In the first expression, 6 tens ÷ 4 tens, we are dividing the value of 6 tens (60) by the value of 4 tens (40). The result is 1.5.
In the second expression, 6/5 ÷ 4/5, we are dividing the fraction 6/5 by the fraction 4/5. Dividing fractions is the same as multiplying the first fraction by the reciprocal of the second fraction. So, it becomes 6/5 x 5/4. The result is also 1.5.
