Answer 2

Answer:

Step-by-step explanation:

3) Let y=unknown

⇒(55/12)+y=13/2

⇒y=(13/2) - (55/12)

     =23/12

∴(55/12)+(23/12)=13/2

⇒(4¹/₁₂) + (1¹¹/₁₂)= 6¹/₂

4) a) 11/100 × 25=275/100=11/4

   b) (3×(1/8) ) × (15/9)=3/8 × 5/3=15/24=5/8

   c) (5/6)×6³/₅ =(5/6) × (33/5)=165/30=11/2

   d) (3/8)×(3¹/₅)×15=(3/8)×(16/5)×15=(48/40)×15=(6/5)×15=90/5=18
