What is the product of 5 7/10 - 5/18

244/45

Step-by-step explanation:

Simplify the following:

5 + 7/10 - 5/18

Put 5 + 7/10 - 5/18 over the common denominator 90. 5 + 7/10 - 5/18 = (90×5)/90 + (9×7)/90 + (5 (-5))/90:

(90×5)/90 + (9×7)/90 + (5 (-5))/90

90×5 = 450:

450/90 + (9×7)/90 + (5 (-5))/90

9×7 = 63:

450/90 + 63/90 + (5 (-5))/90

5 (-5) = -25:

450/90 + 63/90 + (-25)/90

450/90 + 63/90 - 25/90 = (450 + 63 - 25)/90:

(450 + 63 - 25)/90

| 1 | |  

| 4 | 5 | 0

+ | | 6 | 3

| 5 | 1 | 3:

(513 - 25)/90

| | 10 |  

| 4 | 0 | 13

| 5 | 1 | 3

- | | 2 | 5

| 4 | 8 | 8:

488/90

The gcd of 488 and 90 is 2, so 488/90 = (2×244)/(2×45) = 2/2×244/45 = 244/45:

 244/45

38.5

step-by-step explanation:

lets say, first number = r

second number = 3r+7

total = 49

(r)+(3r+7)= 49

4r+7 = 49

4r = 42

r = 42/4

r= 10.5

3r+7 = 3(10.5)+7 = 38.5
