Answer:

• 5/3+7/51 of 7/5-5/3 = -368/765 = -0.48

• 2/9×5/7 of 28/5-2/3 = 148/189 = 0.78

Step-by-step explanation:

1) 5/3+7/51 of 7/5-5/3 _____

= 5/3+7/51 × 7/5- 5/3

= ((5×17)+7)/51 × [(7×3)-(5×5)]/15

= (85+7)/51 × (21-25)/15

= 92/51 × (-4/15)

= -368/765

= -0.48

2) 2/9×5/7 of 28/5-2/3

= 10/63 × ((28×3) - (2×5))/15

= 10/63 × (84-10)/15

= 10/63 × 74/15

= 2/63 × 74/3

= 148/ 189

= 0.78

hope it helps you :)
