Answer» Answer: 5/4 Step-by-step explanation: RENU completed 2/3 PART of her home work in 2 hours. Let us assume TOTAL part of homework be ‘P’. Then, 2/3 of P = 2 2/3 × P = 2 By cross MULTIPLICATION we get, P = 2 × 3/2 P = 3 home work So, part of her home work had she completed in 1¼ hours i.e. 5/4 hours |
