Answer 1

5/4+6/5+7/6+8/7+9/8+10/9= 3150/2520+3024/2520+ 2940/2520+2880/2520+2835/2520+2800/2520= 17629/2520= 6 2509/2520

Answer 2

To find the value of the given expression, simply calculate each term and then add them together:

1/4 × 5 = 5/4 = 1.25 1/5 × 6 = 6/5 = 1.2 1/6 × 7 = 7/6 ≈ 1.16667 1/7 × 8 = 8/7 ≈ 1.14286 1/8 × 9 = 9/8 = 1.125 1/9 × 10 = 10/9 ≈ 1.11111

Now, add all these values together:

1.25 + 1.2 + 1.16667 + 1.14286 + 1.125 + 1.11111 ≈ 6.91064

So, the value of the expression is approximately 6.91064.
