Question 467513
I will say for now that total number of flowers = {{{1}}}
(1) {{{ 13/30 + 2/5 + g = 1 }}}
{{{ 13/30 + 12/30 + g = 30/30 }}}
{{{ g = 30/30 - 25/30 }}}
{{{ g = 5/30 }}}
{{{ g = 1/6 }}}
This is the fraction of the total 
that are gladioli
----------------
Multiply both sides of (1) by {{{t}}},
the actual total number of flowers
{{{ t }}}
(1) {{{ (13/30)*t + (2/5)*t + g*t = t }}}
(1) {{{ (13/30)*t + (2/5)*t + 7 = t }}}
(1) {{{ t - (13/30)*t - (12/30)*t = 7 }}}
(1) {{{ t*( 1 - 25/30) = 7 }}}
(1) {{{ t*(5/30) = 7 }}}
(1) {{{ t = (30/5)*7 }}}
(1) {{{ t = 42 }}}
There are 42 total flowers
