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 :)
