5 37/40 as a decimal
Luden [163]
Well 5=5
and 37/40
hmm, try to get that 40 into an nice number that is multiplule of 10
if we divide top and bottom by 4 that would work
( \frac{37}{40})( \frac{ \frac{1}{4} }{ \frac{1}{4} })= \frac{9.25}{10}
9.25/10=92.5=100=925/1000=925 thousandths=0.925

so the decimal would be 5.925

if PQ=21 cm and QR=5cm, then what are the possible lengths for PR so that line PQ, line QR, and line PR can form a triangle? exp
postnew [5]
PR must be less than 26cm as PQ + QR = 26cm

PR must be more than 16cm as PD- QR = 16cm

At both those limits the sides would lay on top of each other.
