Question

Sanchi reads a book for 14/5 hours everyday. how many hours were spent if he read the whole book in 7 whole by 1/2​

Answer 1

Step-by-step explanation:

$hello \: \\ your \: friend \: here \: \\ looking \: like \: you \: are \: facing \: some \: difficulty \: in \: this \: particular \: solving \: \\ but \: you \: do \: not \: worry \: at \: all \: we \: together \: shall \: solve \: \\ my \: only \: request \: to \: you \: is \: to \: have \: a \: good \: look \: over \: the \: answer \: and \: you \: definetely \: will\: do \: it \: \\ right$

$so \: we \: know \: that \: in \: \frac{14}{5 } \: hours \: sanchi \: reads \: in \: 1 \: day \: and \: the \: question \: is \: in \: 7 \times \frac{1}{2} days \: how \: many \: hours \: will \: he \: complete$

$= )\frac{14}{5} - - 1 \\ x - - 7 \times \frac{1}{2 } \\ = )now \: by \: cross \: multiplication \\ = )and \: by \: changing \: 7 \times \frac{1}{2} in \: simple \: fraction \: = \frac{15}{2} \\ = )1x = \frac{14}{5} \times \frac{15}{2} \\ = ) \: now \: here \: we \: can \: see \: that \: the \: fractions \: can \: be \: simplify \: \: so \: 2 \times 7 = 14 \\ 5 \times 3 = 15 \\ so \: the \: obtained \: number \: is \: \\ = )7 \times 3 \\ = )21$

$so \: here \: one \: thing \: that \: you \: need \: to \: understand \: in \: perspective \: is \: to \: understand \: that \: book \: number \: or \: value \: given \: really \: does \: not \: \: matter \: here \: alright \: now \: let \: us \: move \: forward$

There you go your answer is 21

Hope it helped you
